Abstract: In an apparatus for depositing thin layers of paints, inks and other liquid materials in accurately defined areas on surfaces, having a number of reservoirs (33, Fig. 1) for the liquid and means for feeding the liquid to a number of cavities in a matrix 5, against which the surface to receive the deposit is brought and held in pressure contact, the feeding means comprises a plurality of similar pumps assembled as a unit 20 and mounted on the machine separate from the matrix, individual pumps being connected by suction tubes 32 with the reservoirs and by delivery tubes 9 to passages through the matrix to the cavities in the operative face thereof, the delivery stroke <PICT:0859775/III/1> <PICT:0859775/III/2> <PICT:0859775/III/3> of the assembly of pumps being effected simultaneously by fluid pressure in a manifold common to all the pumps of a unit.  More than one pump unit 20 may be used, a common supply fluid line 51 being provided for all the manifolds.  As shown in Fig. 5, the pumps may be hydraulically actuated and each comprise a plunger 37 sliding in a chamber 25 formed in a block 22 common to the unit; non-return valves 35, 36 allow entrance of liquid from pipe 32 and delivery through pipe 9 respectively.  The plunger 37 extends into a channel 23 formed in a member 21 and is urged by a spring 38 against a further springloaded plunger 43 which extends through a bore in the member 21 into a chamber 40 therein, to which hydraulic liquid is led from the pipe 51.  Individual pumps may be inactivated by reversing the plugs 28.  The supply of hydraulic fluid to the pump unit is controlled by a valve comprising a spool 56 movable in a cylinder 52 under the control of a cam 59 on a shaft 16, so that the pumps are operated in timed relationship with the movements of the platen 12.  An alternative form of pump, for pneumatic operation, comprises a body 67 formed with a number of bores 68, each closed by a plug 69 and communicating through passages 70, 73 and nonreturn valves 72, 75, with the pipes 32 and 9 respectively.  A piston 76 is carried by a bellows 77 which is sealed to the chamber at 78, the interior of each bellows being in communication with a manifold 80. Admission of compressed air to the space inside the bellows causes the latter to expand, forcing liquid into the pipe 9, while the creation of vacuum causes collapse of the bellows and recharging of the pumps. Specification 821,152 is referred to.

Abstract: 904,911. Baling-presses. PLESSEY CO. Ltd. May 4, 1959 [May 12, 1958], No. 15102/58. Class 94(1). The size of the exit from the baling chamber of a hay or like baler is controlled by a probe which engages the bale and operates a valve in a connection between a source of pressure fluid and the cylinder of hydraulic means for moving a wall of the bale passage. The probe, a wheel b 1  is carried on a valve spool c operating in a housing h mounted on the moveable wall g. A piston ei is connected to the wall. In the neutral position shown, fluid from a pump s escapes back to a pump d via passages j, j1. ' Should bale density decrease, the probe descends so that valve bands c 0  and C1 cut off the passages j, j1 from the pump supply which then passes through a diagonal bore r to a passage q leading to a relief valve f. The valve f is depressed and fluid enters above the piston e1 carrying the wall g to be pressed inwards. This lowers the housing h and restores the housing and valve spools to the relative position shown. Should bale density increase, the probe rises, lands C 1  and c 2  cut off passages j, j1 and pressure fluid flows through a bore I to above an auxiliary piston p via a passage m. This descends, opening the valve / and permitting fluid to escape from above the piston e1 via passage j1. The wall g and housing h rise until the neutral position is again reached.

Title: Method and device for cooling the lubricating oil of internal combustion engines
IPC: F01M5/00
Filed: 1938-05-20
Abstract: 515,020. Lubricating. MORTIER, H. May 20, 1938, Nos. 15151 and 15152. Convention dates, July 22,1937, and Sept. 28,1937. [Class 12 (iii)] In an aircraft or other engine the oil radiator 14 is in thermal contact over a large surface with the tank 6 from which the engine draws in its supply of lubricant. As shown, hot oil from the engine returns at 8 to a regulator 7 located within the oil tank 6. The regulator is of the kind described in Specification 477,939. Air present in the oil separates out and escapes through perforations 10 and a vent pipe 11. If the oil is relatively cold the throttle 18 is open and the warm oil returns to the engine by a pipe 13. As the oil warms up the throttle 18 gradually closes and more of the oil ascends round the outside of the pipe 12 of the regulator and passes through a pipe 16 to the radiator 14. If the oil in the radiator is congealed oil in the pipe 16 passes to the tank 6 through small holes 17. The oil in the radiator 14 is warmed by that in the tank 6. Ultimately the throttle 18 closes and the oil in the pipe 16 passes through the radiator 14 and thence through a duct 19 and the tank 6 to the outlet 13. The tank 6 which has ribs 15 may have inclined air ducts 26 extending therethrough so that much air passes through these ducts when the aeroplane is rising and little when the aeroplane is diving.
